Bold 9780 in a Re-Boot Loop

My Bold 9780 is stuck in a re-boot loop after installing the BBM connected Travel Manager app.  I've tried hard and soft manual re-boot of the device but still no luck.  It won't get past about 2/3rds or 3/4 rebooting before it loops back and starts the process again.  Any ideas?

Re: Bold 9780 in a Re-Boot Loop

Dear Admin.


Please help me out.


My BB-9780 was showing an error after start up which read as "Uncaught exception: java.lang.Error" which used to go after pressing OK.

It was since last 2 weeks, and i felt device had also gone slow since then.


Today morning i took a backup of contacts, calender and performed a wipeout. I had kept the device connected to my workstation to make sure battery does not goes while wipe-out.


After wipeout the actual problem started, the phone restarted with BlackBerry logo & progress-bar but It doesn't completes & get past about 2/3 or 3/4 rebooting and then it loops back and starts the booting process again.


I searched http://crackberry.com/blackberry-101-lecture-12-how-reload-operating-system-nuked-blackberry but there is no blackberry apploader in my system. also the OS which was in my device is not available online on page https://swdownloads.blackberry.com/Downloads/browseSoftware.do;jsessionid=DE21B633213AE4B3ADAEC17133...


I bought this device with lots of hopes and it has helped me a lot. I won't be able to afford a new one.

Download and install the latest from any carrier, it doesn't have to be your own:



After installing it, use this program, it will delete the vendor.xml files so that you can install the OS from another carrier:



Then follow the guide.
